Application filed March 6, 1914. Serial No. 823,009.

To all wh om it may concer/a lie it known that l, Grenen R. SHIPMAN, a citizen oit the United States, residing at Nor-tolk, in the county of Norfolk and State of Virginia, have invent-ed new and useful Improvements in Fenders for Ships, ot which the following` is a specification.

The invention relates to safety devices for water craft, and more particularly to the class of tenders for ships, boats, or the like.v

The primary object of the invention is the provision olf a tender wherein the same will avoid or lessen. the dan'iagc to the hull or body of the ship, boat, or the like, on the same contacting with an object, either in eollision with another vessel, or while landing at docks or terry slips.

Another object ot' the invention the provision of a tender which can be readily and easily applied to the hull ot a ship so as to protect the same, and which is oi novel form.

A. Yfurther object ol the invention is the provision of a fender oit this character which is extremely simple in construction, thoroughly reliable and etlicient in its purpose, and inexpensive .in manufacture.

With these and other objects in view, 'the invention consists in the construction, coinbination and arrangement of parts as will. be hereinait'ter tally described, illustrated in the accompanying drawing', and pointed out in the claims hereunto z'tl'ipended.

In lthe drawing: Figure l is a fragmentary side elevation of a ships hull, showin, l the tender constructed in accordance with the invention applied thereto, the bow ol the ship bei ng shown. Fig'. Q is a sectifnlal view on the line Q 2 oit Fig'. -l. Fig. 3 a top plan view. Fia'. 4t .is a top plan view showing the stern oil the ships hull with the fender applied thereto. Fig'. 5 is a :fragmentary sectional view on the line 5-5 of Fin'. l.

Similar reference characters indicate correslionding' parts throughout the several views in the drawing.

Referring' to the drawing in detail, A designates a portion ot a ships hull, which may be ot' the ordinary well-known construction, and B the safety t'ender 'onstructed in aeeordance with lthe invention, and hereinafter 't'ully descril'ied.

The safety fender comprises a suitable frame 5, preferably made from metal, the

saine being bent to extend about either the how or stern ot the hull of the ship, and is formed with end plates 6 through which are passed suitable 'fasteners for the scouring' o'lf the 'lranle in position on the hull as shown.

The numerals T and S designate upper and lower bearing,r [langes o'l. the iframe 5 in which are engaged the journal ends 9 of rollers 1,0 which are arranged in spaced parallel relation to each other, the rollers being; constructed trom any suitable material to withstand shocks when contacting,r with an object such as a vessel, wharf, doek, or terry slip. The rollers may be varied with respect to their length, and also can be arranged close or separated any desirable distance apart within the supporting' frame there-tor. The rollers l0 avoid or lessen the damage to the hull of the ship in event of collision with another vessel or while landingr at docks or 'lerry slips.

.-ltrrangr'ed rearwardly et' each roller 10 in termediate the ends thereof is a reinforcing seamental-shaped abutment 1l formed with a base Ali adapted to be secured to the ships hull, and in this al'nltment is provideda raceway I3 in which are arranged a series o'l bearing,l balls lai with which is adapted to contact the roller adjacent thereto should excessive strain he exerted upon the same, so as lo avoid thc cracking' or breaking of the roller under sudden coneilssion when striking; an obstruction.

lhe journal ends 9 ol the rollers l0 have arranged cmicentrically thereto bearing' balls which are suitably supported and removably held in the bearing; flanges of the, frame 5 so that :friction is reduced to a minimum, thus permitting; the rollers to freely rotate when eng'agg'ilug a txe'd structure or coming' in contact with an obstruction.

lt olf course to be understood that the alnitn'ients l-lf can be increased in number should the rollers l() be ot' lengths to require the saine.

lhe iframe at opposite ends thereof has outwardly flared portions 1G which .serve to deilect small obstacles against the outermost rollers oi the series and thereby preventing the same from working through the frame to the rear ol? the rollers.

.From the foregoing it is thought that the construction and nnmner oi use oit' the device will be clearly understood, and therefore a more extended explanation has been omitted.

`What is elaiined is l. The Combination with a ships hull, oil a plurality of rollers journaled eXteriorly thereof at one or more points of the saine, the said rollers beingdisposed vertically and in close parallel relation to each other, frames for rotatably supporting the rollers and adapted to be xed to the said hull, an outwardly flared portion on the frame at the outer side of the outermost rollers to serve in deleeting small obstacles against the latter for preventing the said obstructions from working between the rollers and the frame.

2. The Combination with a sliips hull, ot a plurality of rollers journaled exteriorly thereof at one or more points of the same,

.and the rollers and 'formed with raeeways, uid bearing` balls arranged within the raceways and working' against said rollers intermediate the ends thereof.

ln testimony whereof l affix my signature Lv in pres-ence of two witnesses.
